Detroit police are currently investigating the possibility of child abuse after Charlie, who had been reported missing for 11 days, was found alive in the basement of his father, Charlie Bothuell IV, and stepmother’s townhome in Detroit. His father says he had no knowledge his son was down there and that he and authorities had searched that location multiple times.

According to Fox 2, Child Protective Services released the boy to his biological mother Thursday after he received medical treatment and after he was interviewed by psychiatrists and investigators. The extent of the boy’s injuries, if any, has not been made known.

Young Charlie reportedly told investigators his stepmother fed him and helped him hide, and that he was in the basement for the entire 11 days he was reported missing. Maintenance workers at the housing complex tell Fox 2 they believe that is not possible.

Inside the Bothuell family’s townhouse police found traces of blood in young Charlie’s room and on his clothes, and a PVC pipe the father admitted he used to discipline his son was taken as evidence.

Fox 2 reports investigators are testing the blood found in the town-home to see if it belongs to the other two children that lived in the house, Charlie’s half-brother and half-sister. Those two children are the ones that have been removed from the home.

Monique is said to be in custody for probation violation for a weapons charge. In 2013, she was arrested and convicted of carrying a concealed weapon without a valid license and sentenced to probation. When authorities searched her town-home they found a gun, which violated her probation, and issued a bench warrant.
